Active Noise Barrier

Noise barriers


Although traditional noise barriers have proven their effectiveness in protecting homes against road noise, they still have weaknesses in the low and medium frequencies.

By producing counter-noise in real time at the top of the wall, the innovative approach developed by TechnoFirst makes it possible to significantly increase the size of the “shadow zone” behind the wall.
